It won't harm anything, but on an OBD2 car, the ECU will throw a code eventually.

there's a good chance your ecu'll throw a CODE for fuel system leak.
Shouldn't be bad in anyway though.

Go to a gas station and say you lost one for your car. They will pop out a bunch of them and just pick which one is yours

LOL...have you actually done this? I'm sure they do have tons. You will get bad gas mileage if you leave it off.

Wouldn't your fuel pressure go down since it's a sealed system? No more "hiss" from opening the tank...doubt it's a biggie, though.
